Abstract
A reversible image display panel which comprises a pair of substrates one of which is transparent and a group of particles charged with single polarity, a group of particles with single color charged with single polarity, a group of particles having portions with different colors and different charge characteristics, or two groups of particles with different charge characteristics each enclosed between the substrates, characterized in applying an electric field across the substrates, and displaying images by flying and moving the particles. The reversible image display panel and the image display device in accordance with the invention have fast response speed and simple structure, being superior in stability and vividity. In an occasion of driving, generation of the strong electric field is unnecessary for them and accordingly, electric circuits can be assembled employing general purpose electronic materials.
